Question

A window is shaped like a semicircle with a diameter of 5.2 feet. What is the area of the window? Round to the nearest tenth.

Answer 1

D. 10.6 ft2

Explanation:

Answer 2

Area of semi-circle formula: A = πr²/2

_______

Let's find the radius by dividing the diameter by two: 5.2 / 2 = 2.6ft.

_______

Now, let's solve for the area.

A = (3.14)(2.6)²/2 ft.

A = (3.14)(6.76)/2 ft.

A = 21.2264/2 ft.

A = 10.6132 ft.

_______

Now, we can round.

10.6132 → 10.6ft.

_______

The area of the window is approximately 10.6 feet.
